The day after Rias and Mio was freed form their unwanted engagement, the former was very clingy to Y/n at school. This caused a lot of rumors to spread around the school and a lot of rage form the male students, sadness from the female students. 

Issei's perverted friends tried to attack Y/n out of jealously, but Y/n just grabbed and bashed their heads together. Issei himself is also jealous, but knows better then to attack Y/n, not only will Rias punish him but Y/n can also easily roast his rear into crisp.

After school, the ORC all gathered at Y/n's new mansion. There Y/n will meet his new peerage and team. They were all at the living room, a orange magic circle appeared and a group of fifteen girls emerged from it.  Seeing Y/n, the queen stepped forward and introduce herself and the peerage

"Greetings lord Y/n, my name is Yubelluna, your queen."  Yubelluna greeted, she then began to introduce the other members.

"First are your Bishops, Mihae and Lady Ravel." The Bishops step forward.

"Your Knights, Karlamine and Siris." The knights also step forward.

"You Rooks, Isabela and Xuelan." They stepped forward.

"For your Pawns, you have two sets of twins, first is Ile and Nel." The green haired twins stepped forward.

"The other two are Ni and Li." The two cat girls step forward.

"The ones that are dressed as maids are Marion and Burent." The maids step forward

"Finally, the remaining two are Mira and Shuriya." The final pawns stepped forward.

"We're in your care Lord Y/n, please treat us well." They said in union before bowing.

"N-now now, you don't have to call me lord, just call me Y/n." Y/n said uncomfortable of being called Lord.

"Lucky son of a...." Y/n could hear Issei hiss in jealously.

"Koneko, if you please?"

"Roger." As all Koneko said before she smacked the pervs head to the ground.

"Now that your introduced to your peerage Y/n, there's mail for you." Rias said as she handed him a letter and a package.

"A letter? Let see...."  Y/n said as he accepted them. 

"Who's it from?" Rias as curiously.

"It's from a my cousin from overseas,  he sent me some souvenirs from Egypt." Y/n said as he opened the package. Inside was two interesting items.

Y/n opened the box to see, puzzle pieces? Deciding to solve it when he has the time, he placed both items aside. He then turned to his peerage.

"I can tell your still tired from moving, so you girls have the rest of the day off. Please make yourselves at home."

They nodded, happy to have a kind and caring king after their last one was a lousy one.

The rest of the day was Y/n getting know his peerage, learning their interest and such. But for some reason,  he heard both Ile and Nel laughing when he passed by their room. He did lent them some Home alone movies, but there's no harm in that.... right?

 About a hour later, he saw Issei knocked out at the bottom of the stairs, he looked up to see a filled paint can tied to the top with rope and the twins laughing away. Their in front of him a minute later.

"Okay girls, as funny is it is, you should't use the traps on him."

"Aw~" They whined

"But if he does something stupid, i can let you two prank him all you want, even give you ideas of traps of your own."

"Yay!" They cheered as they hugged him.

After a few hours, they were at in front of a abandoned building. 

"Y/n, hiding somewhere in this abandoned building as whats known as a stray devil, devil servants that had diverted away from their masters for their own selfish desires. Without their masters to keep their powers in check, they become a great threat if their powers go beyond their control." Rias explained. "It's our job deal with them when one appears, capture or destroy, but it usually ends up the latter."

"You and your peerage will eliminate this one." Akeno said." We'll watch from the side and will step in if needed but i doubt we'll need too." She giggled .

Y/n nodded before entering the building with his peerage, they didn't have to look for the stray as they saw a giant spider like monster crawling around between the floors.

"Ugh, gross."

"Indeed, when a devil servant goes stray, that aftermath is never pretty." Ravel nodded in agreement.

"Karlamine and Siris, use your speed to slice it's legs to slow it down, Isabela and Xuelan follow closely to bring it to the ground floor, Ravel and Mihae cover them with magic fire. Pawns, get ready in case anything goes wrong"

"Understood!" The pieces said in union before they look action. The knights used their speed to quickly reach the stray while the rooks followed close behind. The stray fired at webs at them, but Mihae and Ravel fired blast of magic to destroy them. 

Karlamine and Siris sliced off it's front legs causing it to scream in pain, the rooks soon followed with heel kick that sent it to the ground floor. It weakly looked up to see Y/n and Yubelluna approach it.

"Any last words?"

It let out a weak cry that Y/n was sure that meant "go to hell". Y/n held up his left arm, it glowed before a red gauntlet with a green gem on it appeared. 

This was the boosted gear, Overlord had introduced Ddraig to him in his mindscape that morning, he informed Y/n earlier that morning and he informed everyone else.

"Yubelluna, shall we?" Y/n asked his queen as a flame appeared on left hand.

"Boost x 5!"  Ddraig called out.

"We shall my king." Yubelluna said as a magic circle appeared in front of her.

"Now disappear!" Both fired a blast of fire and magic at the stray, obliterating it, leaving only a crater where it once was.

"Excellent job Y/n, you did well for your first stray hunt." Rias clapped as she approached. "Lets return to the mansion for some tea shall we?"

 A few minutes later both peerages was at Y/n's mansion having some snacked given by Akeno and the four maid pawns. As Y/n relaxed with his first and new peerages, He could only wonder what the future holds.

Done and done, next time Y/n will encounter a Zeorth dragon for the first time and he'll meet up with a few people from his past. What do i mean? Read to find out
